When a chat is initiated, FlowBridge will send variables to your Voiceflow build which can then be used within the project itself. To be able to use these variables, you will need to create them in the variables section of your Voiceflow project. So if you want to get the channel the user is communicating on, you can create a variable called "channel" (without the quotes) in Voiceflow. These are the variables we send:

• channel This can be one of the following: "whatsapp", "facebook", "instagram" or "webchat"
• user_name This will be the name of the user. We only receive this for the WhatsApp & Telegram channels channel. It will be set to 0 if it's not WhatsApp or Telegram
• phone_number This is the number of the user without the "+" prefixed. This will only be set if the channel is WhatsApp
• telegram_id - For telegram integration channels, the telegram_id variable will automatically be populated with the telegram id of the user sending the message
